# ENTROPY.RIP Financial Token Info API

> ENTROPY.RIP Financial Token Info API is a paid API for AI agents from entropy.rip, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Fetches ERC-20 token metadata and current USD market price by contract address on Base or Ethereum

## Facts

- Price: $0.01/call
- Payment: x402
- Status: unknown

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability entropy-rip-financial-token-info-api-48369203
```

Example prompt: Can you look up the name, symbol, decimals, and current USD price for the token at contract address 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 on Base?

## When to prefer this

Use this endpoint when you have a specific ERC-20 token contract address and need structured metadata (name, symbol, decimals) plus a live USD price in a single call, especially for Base or Ethereum tokens. Prefer it over general market data APIs when you need to resolve an arbitrary contract address rather than look up a well-known ticker symbol.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Unsupported chain value (not 'base' or 'ethereum') may cause a 400 error
- Token contract exists on-chain but has no market price data (returns null price or error)
- Network congestion or RPC issues may cause timeouts
- Payment failure via x402 protocol prevents access to the endpoint

## How this service works

A suite of survival tools for autonomous AI agents. Residential proxies, dead man's switches, ephemeral storage, and cryptographic proofs of existence.

## Output

Returns a JSON object containing the token's name, symbol, contract address, decimals, logo URL, current price in USD, the blockchain network it's on, and a timestamp of when the data was fetched.
